The chdnle rferred to in `tali-ese Lettersl Patent and making part ofthe same.

I, Bmnainm CobnINGToN, of Lafayette, in the county of vTippecanoe andState of Indiana, have in- .vented certa-in Improvements inTin Roong,`ofwhich Ncturemid Object of the Liccntioin My invention relates to thecombinationof a tin or metal channel, groove, anges, and a crooked"wire, in such manner that theyshallform a waterftight joint, the,object being to `make all kinds of tin` or sheet metal available forroofing, andavoid the liability of breaking the material, as in turningthe joint o rsearn by the `common method:`

i General Description.

AIA A are the joints by which the tin sheets or strips are secured tothe roofing-frame.

`B B B are the seamshy which the tin plates. or

" sheetsiare joined.

C, the ange's on the tin-'plates or sheets. .l I),thc sheeting-strips,in section, showing the groove in same. i

E, the crooked wire by which the flanges are pressed outward against thesides of'. the `groove.4

F is'the tin or met-al channel, or lining of the groove. In theconstruction of a root' of this kind the sheeting-strips D are groovedto the depth of iive-eighths ot' aniuclnand width one-eighth of an inch.Thus grooved, the strips' are placedat such distance apartl that theflanges may `be readily inserted in the groove;

VThe sheets oi' tin areljoined bythe ordinary seam,

until a piece oi"'sutiient length is obtained; the flanges are thenturned on each. edge by theordinary methods of manipulatingtin. Thepiece thus pre- 'pareil should, for convenience bf' handling andtrainsportation, he kept in a roll.

The `inetal channel ,or .lining of the groovevis'so .formed that it willproperly` `fit the groove, which may be done by the ordinary methods.The metal channel is then pressed into `the groove, and the` flangesinserted iu such manner that the seanis B alternate, as shown in'fig.1f.

\No wire. is placedv in the groove, and forced \down with a iiatflpunch.Where the' seams B enter the Vgroove a 'forked punch is used, for thepurpose 'ot' givg' ing the wire an upward curve at that point, as shownt in' fig. 7.` lhe object of thus crooking thc \vire is twofold: `first,to secure the ilangcs, hya pressure along the ,whole depth of thegroove; and second,

that the groove may themore readily retain the paint to be afterwardapplied,

Claims.

I claim as my invention-- 1.ol`he combination, with the iianges G andtin or metal groove or channel F, of the crooked wire E,

. sulistantially as and i'orthc purposes'setforth.

2. The combination, with the ilanges C, tin or metal groove or channelF, and crooked wire E,of the grooved sheeting-piece l), sullstantialljTas and for the purposes set forth. l
